The new resources are the result of a multi-year co-investment between MLA and AWI aimed to improve lamb survival and reproductive rates in the Australian sheep flock through better adoption of pregnancy scanning.
The background research was completed by The University of Adelaide and included many industry consultants in the project team.
In 2018, an MLA-funded survey of Australian sheep producers determined that 69 per cent of respondents did not pregnancy scan their ewe flocks for litter size.
According to MLA project manager for sheep and goat productivity Dr Daniel Forwood, this limits a producer’s capacity to maximise lamb and ewe survival.
“Pregnancy scanning is a vital tool for improving sheep reproductive performance,” Dr Forwood said.
“It enables identification of litter size early in pregnancy, so that multiple-bearing ewes can be differentially managed to meet recommended condition score targets and increase survival.
“Research shows pregnancy scanning in sheep provides an average increase in profit of $5.55 per ewe scanned.
“By customising ewe nutrition during pregnancy and lactation according to whether ewes are carrying singles or multiples, producers can help to reduce lamb and ewe mortality.”
As part of the project, AWI general manager for research Bridget Peachey said AWI and MLA conducted an extensive benefit cost analysis on the value of scanning across a range of sheep producing regions and enterprise types.
“In addition, the two organisations undertook a series of grower interviews and surveys to create a better understanding of the barriers to adoption of pregnancy scanning, then develop solutions to overcome these barriers,” Ms Peachey said.
“Important to increasing producer adoption is having a detailed business case for pregnancy scanning which is applicable to different production environments and enterprise types, producer needs and resource availability.”
The resources include the following:
• The value of pregnancy scanning
• Ewe scanning and management checklist
• Pregnancy scanning: an ultrasound investment
• Resource guide for sheep reproduction
• The value of pregnancy scanning: a benefit-cost analysis
This project is an initiative under the Sheep Reproduction Strategic Partnership (SRSP).
